Comment (by rianrietveld):

 In [https://make.wordpress.org/accessibility/2014/10/15/time-to-test-
 twenty-fifteen/#comment-72215 my theme review] I checked this and the
 colour contrasts pass WCAG 2 AA ( used a Colour Contrast Analyser for the
 opacity, see http://www.paciellogroup.com/resources/contrastanalyser/)

 There are actually 2 different rules in WCAG  2 AA, for normal text the
 contrast ratio is minimal 4.5:1, for larger text, like headings this is
 3:1. http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-
 contrast.html
 Now big text is defined as 18pt or larger, so how big that is depends on
 the device, a bit confusing to my option.

 I agree with iamtakashi, we do not have to check all the different colour
 schemes, there should be one default good scheme.
